Answer:
your answer is 453
Step-by-step explanation:
The answer is b. 7 is greater than or equal to 6.
So originally, let's say the width of Frank's land was

feet.
The area of his land was therefore

, or

, as his land was square.
The width of his land then increased by 3 feet, and the height decreased by 3 feet.
So the new area of Frank's land is:

So the new land is now
9 square feet smaller, so it is not a fair deal for Frank.
Hope this helps :)
I believe 1 is 3.8, b/c 1.9*2 is 3.8, and the difference between exponents makes 3 zeros, so 2000.
The second one is 40, I confirmed this by doing .0001 to replicate 10 to the negative 4th power
By doing 9.5*.0001*40, I got the 0.038 from 1
Answer:

Step-by-step explanation:
625 when divided by 5 gives 125 which is a perfect cube.
=> 
![\rule[225]{225}{2}](https://tex.z-dn.net/?f=%5Crule%5B225%5D%7B225%7D%7B2%7D)
![\sf \ \sqrt[3]{125} = 5](https://tex.z-dn.net/?f=%5Csf%20%20%20%20%5C%20%20%5Csqrt%5B3%5D%7B125%7D%20%3D%205)
So, 5 needs to be divided by 625 to make the quotient a perfect cube!
